The Concept of Domain Registration
What is a Domain Name?
A domain name is a rare name for a web site, like microsoft.com and invoicera.com. Domain names must be registered. When domain names are registered they are additional to a large domain name register, and information about your site – including your internet IP address – is stored on a DNS server.
DNS stands for Domain Name System. A DNS server is responsible for informing all other computers on the Internet about your domain name and your site address. A domain name in its simplest form is just an Internet Website address. Just as your house or apartment has its own rare identifying address for the post office, so does each and every Website in existence.
The domain name system was originally produced for the assistance of humans. The actual address used by computers is numerical in format and is referred to as an IP, or Internet Protocol, address. An IP address takes the form of four series of numbers separated by periods. An example of an IP address is 215.55.258.145, and as you can see this would not be easy for most of us to remember. So to compensate, the domain “name” system was produced. It’s much easier to remember a website named “XYZ.com” than it is to remember a number such as the one above.
Registering a Domain
Domains can be registered from domain name registration companies such as dotdnr.com. These companies provide interfaces to search for obtainable domain names and they offer a variety of domain name extensions that can be registered at the same time. Domain Name Registration provides registration sets for .com .net .org .biz .info .us .nu .ws .cc and .tv domains. Newer domain extensions such as .biz .info and .us have more choices obtainable as many of the popular domains have however to be taken. While .com and .net domains are well established and recognized, most popular domains with these extensions are already registered.
Most people are unaware but they already use sub domains on a daily basis. The famous “www” of the World Wide Web is the most shared example of a sub domain. Sub domains can be produced on a DNS server and they don’t need to be registered with a domain registrar, of course, the original domain would need to be registered before a sub domain could be produced. Sub domains can be requested from your web hosting provider or produced by yourself if you manage your own DNS server.
Some providers will offer you a rare name under their own name like:
This is not a real domain name, it is a directory – and you should try to avoid it. These URLs are not desirable, especially for companies. Try to avoid them if you can provide to register a domain. Typically these are more commonly used for personal sites and free sites provided by your ISP, you may have seen theircompany.com/~username as a shared address, this is just another way to proportion a single domain and provide users their own address.
